I would also be interested to see if there are any techniques which can help prevent this. I have a friend who is on a Sabre2 170 loaded at 1.2:1, and he has repeated end cell closures (no particular side), with the side dictating the direction of the turn. Usually a 90 or 180.

if I were you, I'd be happy with what you have. I take it the opening are generally soft...right? That's the only time I get them, and am usually happy to have it. It's usually not a problem, unless you can't keep them inflated.

I've put 200+ jumps on my Sabre 2 190 and have had end cell closure on every one. Openings are great, but the 90 deg turns were disturbing at first. Talked to riggers and to PD and was told that the closure was do to its design. As the other responses indicated, slight riser and/or toggle input and they open right away.

I jump a Sabre2 135 with a wingloading of .96 and have over 350 jumps on it. I used to have problems with closed end cells and my slider staying up, but when I was in DeLand, I talked with and got some packing tips from John LeBlanc and Rikster Powell. Unfortunately, seeing these minor changes in person is probably better than trying to write them out, but I'll try my best.

BTW None of these are major adjustments. In fact they may seem like Duh?, but I found my openings improved dramatically when I started to pay more attention to the little details.

Using the manufacture recommended pro-pack (BIG Surprise, huh?), I first made sure my pack job was very neat. (When I watched Rikster pack, it actually looked like the picture in the manual!) When I clear my stabilizers, I leave them out to the side and let them lay toward the nose when I wrap the tail around. (I've seen people wrap the stabilizers in the opposite direction.) I pay extra attention to the smallest one, making sure the D line attached to it stays clear of the other lines (it always liked to move on me ). I also make sure that my nose is symmetrical and exposed. For about a dozen jumps, I even opened the nose (I think Rikster was the one who suggested I try this) by opening the center cell and taking the four on each side slightly away from the center. (It certainly sped up my openings, but I have since found it isn't necessary.) I only roll the tail enough times to keep the canopy under control as I lay it down. I try to get all the air out of the canopy before I start to cocoon it (John suggested that using one roll to create the cocoon rather than a bunch of little tucks can help prevent me from messing with my neat pack job). Continue (as usual) to keep it neat and under control into the bag and be sure to leave enough line out and Voila . . .

Also keep in mind, the Sabre2 is designed to open slower (Thank God), so give it a little time. I found that I was in such a rush to have that full canopy above my head that I wasn't giving it enough time to let it finish opening on its own. (I had gotten used to the openings on the old Sabre. )

I hope this helps, but if you still need advice I would HIGHLY recommend talking to PD. Their customer service has been five star plus. I was extremely impressed that John and Rikster took the time to help me when I visited DeLand and any time I've had a question, PD always does an excellent job either over the phone or via email answering it (and prompt too).

Jumped a Sabre2 190 on Friday...never been under one of those before. End cells were collapsed on opening, too (nice gentle open, though! ). Toggles once and all was good; I wasn't worried but didn't really think about it too much until I started reading here about others who have noticed it on that canopy.

Wish I could help, but the DZO packed it so I have no idea what they did...and as I said, the opening and end cell closure wasn't scary at all. -My landing...well, that is another story!

Did you jump a Sabre2 190, or Tom's Hornet 190? (which we all know is similar to a Sabre2.) Part of why I'm asking is I'm searching these forums for help about how to stop the deployment end-cell closure on my Hornet 190.

For anyone who has not had this lovely experience, I describe it as "the opening is fine, and about the time the opening feels complete and the slider comes down, the canopy makes a hard turn to one side or the other, for ~90, 180, or even 360 degrees."

I have decided the way I know that a toggle didn't just fire during deployment is that a fired toggle would start the turn more gently*. (*based on full-flight simulation; may not accurately simulate this problem at opening.)

Pulling both rear risers or waiting both seem to fix the closure after it has happened. I've been experimenting with different pack jobs to try and fix it (understanding that what I may be fixing is subtle details in my pack job, not the canopy), but it's beginning to look like I either need to learn to fly the opening or I need to pucker up and live with it.

My sabre2 usually turns at the end of the opening too. Really hasn't bothered me much. But on my last jump I did have a toggle come unstowed, and at first I thought it was a normal opening. When the turn continued, I looked up expecting to see a closed end cell but the canopy looked normal. Then the spin got fast and I realized it must be a toggle. But yeah, the turn started off very gentle.

I'm glad for this thread...I'm a newbi renting gear and each opening has had both fully collapsed, on heading and nice and soft compared to my old 230. I thought it was me...After letting go of the risers on opening, I just pull down the brakes for a second, no turns at all. More issues with the different slider collapsing cords...can't pull em with gloves on. thanks all who have posted here...It's very reassuring to read all of your comments!
